To all of you who have commented (and emailed)
We (Geodesa / GeoSIM) are working on the online rate calculator as "we speak". Be assured we have nothing to hide in the rates, it's just a mater of time and resources!
The
www.globalsimcard.co.uk website will be updated soon with a claculator as soon as is has been fully tested and checked.
Thaks for your patience.
